# Note: jade is changing its name to pug (https://github.com/pugjs/pug/issues/2184)
# This appears to be a work in progress -- the pug-lang domain is parked, while
# the jade-lang one is active. This highlighter will recognize .pug and .jade extensions,
# http://jade-lang.com (will be http://pug-lang.com)
